I think so: 1) Extract microcodes from BIOS

How to add CPU microcode support to existing CPU microcode in current BIOS which I can extract using amibcp?

I think so:
1) Extract microcodes from BIOS to file
2) This file contains microcodes one after another....
3) So if we copy all needed microcodes to one file, we will get "normal" microcode module file
(or use reall.cod file instead of creating it by_hand)
4) Than insert it into BIOS

But this is ONLY GUESS!!!
